We are moving the office to another location.  Wondering what's required from Internet carrier's stand point?  Do they change the public IP, we move their router to the new office, plug it in, and all should work?  This is AT&T service called uVerse.
Thanks in advance!

Tiras25,

Pre-req:

1. Determine how many and what devices you have connected to public IP address
2. Determine Firewall rules that may be pointing to Public IP address
3. Ensure you have access to your Purchased Domain's DNS website such as Go Daddy or network solutions or register.com


Your ISP will provide you another range of Public IP address (for your sanity I would recommend that it was a static address)


1. Make sure that you change all your external facing devices using Public IP to the new address range
2. Make sure to change all firewall rules associated with those devices to the new public address range
3. Make sure that change all NAT policies to reflect the new address range
5. Make sure that you change any MX records to reflect the new Public IP address of your Mail Server
6. Make sure that you Change any DNS entries to reflect those of your new ISP

Thanks man.  There is an opportunity the existing group of people can share their Comcast cable internet.  They are a larger group (about 10 people) and the firm moving in is only for 6 months.  Would that be okay to share the larger group internet connectivity and make some small 'separation' or firewall?  Assume they trust each other not going into each other files.
What do you think?  THe client just doesn't want to spent much $ for that since only for 6mo and the last bus place before the retirement.

Tiras,

I don't see an issue doing that.. You would need to purchase a cheap routing device in order to do this.

A sonicwall TZ100 would be as cheap a device as I would go. You would then need to put your original router on a switch or assuming it has a opt port you could use that.

After that just connect your network as usually creating the necessary NAT and firewall Policies to allow outside connectivity.
